Description

When requesting the frame extents with _NET_REQUEST_FRAME_EXTENTS of an unmapped window that is hinted via _MOTIF_WM_HINTS to be undecorated, Xfwm4 reports the frame extents of a decorated window. Once the window has been mapped, the correct all-zero frame extent is set to _NET_FRAME_EXTENTS.
